Jeep Cherokee 4 wheel drive

I need a little insight on our 4 wheel drive systems. I have the command-trac transfer-case, does that mean when I put it in part time both my differentials are locked?

Anyway here's the story, I went mudding withing a Ford Ranger with Mud Terrains and a Dodge Ram with all terrains. I have a completely stock Cherokee with road tires (keep that in mind,) I also kept the transfer-case in part time. All out vehicles had about 30psi in the tires when we went through the sand, both ended up getting stuck, but I was the only one who got through the sand with ease? The next part surprised the crap out of me, both trucks went through a muddy puddle that just about put the headlights underwater, I went through and I put the whole damn hood underwater and still came out behind them following along (scared the **** out of me, water splashed right up covering the windshield aswell.) That night I ended up losing a license plate, left rear bumper cap and my stock fog lights are filled with water.

Was I able to get through all of this because of how our Jeeps are built or is it a combination of both, knowing how to maneuver a 4 wheel vehicle and how well it's built?

Part-Time 4x4 locks the front and rear axles together.

Driver skills are more important than equipment. It does help that the XJ is lightweight, well balanced, and has lots of low end torque.

Congrats on the wheeling adventures! Jeeps are very capable in the right hands. Water is one of your biggest enemies, The air box is right behind your driver side headlight fyi! Water in intake = hydrolock and or bent/broke rod! Make a snorkel and learn to drive through water. Even shallow water is dangerous if you drive through it too fast. Remember always grease up all your zerks everywhere and check your Diffs and tcase fluids after every time you play in water!

Ok since we have Locked differentials in part time, why do I hear about people putting in stuff called lunchboxes, or other sorts of locking mechanisms in there Cherokees. Whats's that all about? Thats what always confused me.

A locked axle means both tires spin together at the same time on that axle, most differentials are open. A locker enables you to manually lock the differential when you please. Lincoln locking your diff refers to welding (lincoln welder) the spider gears together, I wouldn't recommend welding the front if you drive it on the street. Some rear ends have LSD which stands for Limited Slip Differential. LSD is what it sounds like, When one tire spins or slips too much the LSD engages and spins both together when they work properly.

nice linked, I actually was curious on which was better to do the manual or auto lockers, and also front or rear or both, I have a C8.25 in the rear and a d30 up front, the brake thing works but only part of the time, I would love to have the Front locked just in case, but mine is a DD and dont want to screw things up.

Whatever works for you or fits the budget is best.

Manual lockers nice because they are much cheaper than buying a complete differential unit. A downfall in those is the skill level it takes to install them. If youve never taken apart the internals of an open diff and dont have the correct tools, it can prove to be very difficult. Its not something that can be thrown in and be done with. Since all of the internals are coming apart, you need special tools to measure backlash in the gears as well as backlash between the unit itself with the carrier and bearings themselves. It can be a lot of trial and error messing with shims, torqueing everything and re checking all your measurements. The nice thing about buying a complete unit is the install is a little more straight forward. You still will need to figure out the backlash with the gears and differential bearings, but your not dealing with the smaller internal parts. And if you plan on taking all of that apart, my suggestion is to replace the diff bearings and pinion bearings. Might aswell do it while its all apart than to have to do it at a later date.

You seem to have your terms a bit confused. There are 2 types of differential lockers, automatic or selectable. Some auto lockers can be installed by anybody, in their driveway, with a few hand tools. Commonly these are called lunch box locker such as the Lock Right, Aussie, and PowerTrax No-Slip. Full case automatic lockers like a Detroit and selectable lockers like an ARB require technical skills and specialized tools to install.

If you are not changing gear ratios, a lunch box locker is your best value. If you are changing gear ratios, a full locker and an overhaul of the complete differential with new bearings is your best value.
